哈尔滨市水资源环境承载能力评价

ENVIRONMENT CARRYING CAPACITY EVALUATION OF WATER RESOURCES IN HARBIN CITY

哈尔滨市是全国主要缺水城市之一.为了合理使用水资源,维持水资源的可持续发展状况,维护社会经济,进行哈尔滨市水资源环境承载能力评价研究显得十分必要.本研究分析了水资源环境承载力主要影响因素,采用隶属度函数确定各单项指标隶属度,结合Delphi法得出评判结果矩阵,并采用数据离散化,提高了此评价方法的表达能力.根据水资源环境承载力评价结果,分析了哈尔滨市水资源环境承载力变化趋势,为以后相关研究提供了依据.

Harbin is one of the major water shortage cities in China.To rationally utilize water resources,maintain the sustainable development of water resources and social economy,it is necessary to evaluate the environment carrying capacity of water resources in Harbin.In this study,the main influencing factors of water resources environment carrying capacity are analyzed,the membership function is used to determine the membership degree of each single index,the evaluation result matrix is obtained with combination of Delphi method,and the expressiveness of evaluation method is improved by data discretization.According to the evaluation results of water resources environment carrying capacity,the change trend of water resource-environment carrying capacity in Harbin is analyzed,which provides basis for related research in future.
